Introduction

In order to implement the "vehicle gasoline" standard GB 17930-2013 in the "vehicle gasoline can not be man-made methyl acetal, aniline" And other additives, the proposed method to test the vehicle gasoline contains some typical unconventional additives to meet the market monitoring Pipe needs. Based on the use of unconventional additives found in the automotive petrol market in recent years, the typical gasoline used in this standard The unconventional additives include aniline, dimethoxymethane (methylal) and esters and the like. Due to unorganized environment, traffic and emissions Test to confirm that the use of these additives will be the health of the driver, the safe operation of the car or vehicle exhaust emissions of pollutants Bring about an uncertain impact. So that rapid and effective identification and determination of these unconventional additives in automotive gasoline to protect the interests of consumers and The safety of the vehicle and the effective control of vehicle pollutant emissions is of great significance. The infrared spectroscopy techniques used in this standard have measurements Fast, does not destroy the sample, the analysis of low cost and easy to achieve the characteristics of field analysis. A typical unconventional additive in automotive gasoline Identification and determination of infrared spectroscopy Caution - Personnel using this standard should have practical experience in formal laboratory work. The use of this standard may involve certain hazards Of the materials, equipment and operations, this standard does not indicate all possible safety issues. It is the user's responsibility to take appropriate safety and health measures And to ensure compliance with the provisions of the relevant national laws and regulations.

1 Scope

This standard specifies the use of infrared spectroscopy to quickly identify and determine the automotive gasoline in the aniline, dimethoxymethane (methyl acetal) and esters And other typical non-conventional additives test method. This standard is applicable to the determination of specific unconventional additions in vehicle gasoline and gasoline blending components, identification and determination of the concentration range of additives (3g/L ~ 35g/L, N-methyl aniline 4g/L ~ 35g/L, dimethoxymethane 3g/L ~ 35g/L, sec-butyl acetate 3 g/L to 35 g/L, and dimethyl carbonate 1.5 g/L to 16 g/L. The content of the non-conventional additives in the sample is lower than the above-mentioned measurement range Limit, can not be effectively identified or quantitative analysis. For samples with an additive content higher than the upper limit of the above measurement range, the sample can be diluted appropriately If the sample contains o-methylaniline and p-methyl aniline, according to the measurement of aniline test method to identify and quantify; if the sample Containing other ester compounds, according to the test method of sec-butyl acetate to identify and quantify. But in this case, the precision of this standard is not Be applicable.

3 terms and definitions

The following terms and definitions apply to this document. 3.1 Typical unconventional additions specificnon-regularadditives Typical non-conventional additives referred to in this standard include anilines, N-methylanilines, dimethoxymethane, fatty acid monoesters and di Methyl ester. Note. The above additives are not systematically tested for safety of the environment, driving and discharging tests. 3.2 Anilineecompounds The aniline compounds referred to in this standard include aniline, o-methylaniline, p-methylaniline and m-methylaniline, N-methylaniline. Note. Aniline, o-methylaniline, p-methylaniline and m-methylaniline have similar characteristics of the infrared spectrum, can be identified at the same time, in this method using aniline The N-methyl aniline was identified and quantitatively determined by its unique spectral characteristics. ......
